Since the music data S2 has not been analyzed, the analysis of the music data S2 is started. If the user designates the music display field 603 before the analysis of the music data S2 ends, the music data S3 is selected, the reproduction of the music data S2 is stopped, and the reproduction of the music data S3 is started. In this case, the analysis of the music data S3 is put on standby, and the analysis of the music data S3 is started after the analysis of the music data S2.

  The user can switch between playback start and playback stop by specifying the same music display column. For example, when the user designates the music display field 601, the reproduction of the music data S <b> 1 is started, and when the user designates the music display field 601 again, the reproduction of the music data S <b> 1 is stopped.

  When the user designates any of the plurality of reanalysis buttons 630, selection and analysis of music data corresponding to the designated reanalysis button 630 are instructed. Note that the reproduction of the corresponding music data may be instructed by the designation of the reanalysis button 630. For example, when the user designates the reanalysis button 630 in the music display field 606, the display mode of the music display field 606 is selected, and the analysis of the music data S6 is instructed again.

  In this case, the analysis condition is presented to the user on the display screen 600 or another screen. The analysis conditions include, for example, “analysis without additional information”, “analyze currently extracted tempo as half tempo”, and “analyze currently extracted tempo as double tempo”. For example, the tempo of music data may be extracted as twice or half of the tempo of original music data by analysis. If the tempo extracted from the music data is clearly different from the original tempo of the music data, the user is likely to notice that the extracted tempo is too fast or too slow. In such a case, the user can specify analysis conditions and instruct reanalysis of music data.

  In the example of FIG. 3, the tempo is displayed as 142 bpm as the analysis result 640 of the music data S6. When the user thinks that 142 bpm is too fast as the tempo of the music data S6, the user can designate an analysis condition “analyze as half tempo”. In this case, the music data S6 is reanalyzed assuming that the tempo of the music data S6 is 72 bpm. Further, when the user thinks that 142 bpm is appropriate as the tempo of the music data S6, the user can designate an analysis condition of “analysis without additional information”. In this case, the music data S6 is reanalyzed without analysis conditions. Note that the additional information indicating the analysis condition is not limited to the additional information related to the tempo, and may be additional information related to other music information such as beat points.

  At the top of the display screen 600, a music information display button 650 and an attached information display button 660 are displayed. When the user designates the music information display button 650, the analysis result of the music data corresponding to the music display field in the selected state is displayed on another music information display screen. For example, when the music display column 606 is in the selected state, if the user designates the music information display button 650, the music information display screen is opened. On the music information display screen, the music information extracted by the analysis is displayed in the order of extraction. For example, in addition to the tempo, the chord sequence is displayed in accordance with the bar line and the beat point position.

  The reanalysis button 630 may be displayed on the music information display screen. In this case, the user can instruct reanalysis of the music data by specifying the reanalysis button 630 while viewing the music information displayed on the music information display screen. When the user designates the attached information display button 660, accompanying information such as image data attached to the music data corresponding to the music display field in the selected state is displayed on another screen.

  Above the plurality of music display fields 601 to 608 of the display screen 600, an all music data analysis button 670 is displayed. When the user designates the all music data analysis button 670, the music data S1 to S8 corresponding to all the music display fields 601 to 608 displayed on the display screen 600 are analyzed in the display order regardless of whether or not the analysis has been performed. The When updating the analysis program, etc., re-analysis of all music data is performed efficiently by instructing re-analysis for all music data, rather than giving instructions for re-analysis of music data individually. Is called.

  Further, an end button 680 is displayed on the display screen 600. The user can instruct to stop the reproduction of the music data or stop the analysis of the music data by specifying the end button 680.

(4) Operation Example of Analysis Control Processing FIG. 4 is a diagram showing an example of a reproduction required time, analysis required time, and analysis result of a plurality of music data. The reproduction required time, analysis required time, and analysis result of the music data S1 to S8 in FIG. 4 are stored in the storage device 13 in FIG.

  FIG. 4 representatively shows the tempo of the music information extracted as the analysis result. The tempo extracted by the analysis is stored in the storage device 13 in association with the music data. Other music information extracted by the analysis is also stored in the storage device 13 in association with the music data. In the example of FIG. 4, the analysis of the music data S1, S4, S6 has already been completed. On the other hand, the other music data S2, S3, S5, S7, and S8 have never been analyzed.

  Next, an operation example of the analysis control process based on the state of FIG. 4 will be described. FIG. 5 shows a first operation example of analysis control, FIG. 6 shows a second operation example of analysis control processing, and FIG. 7 shows a third operation example of analysis control processing.

  In the first operation example of FIG. 5, music data S2 to S8 are sequentially selected at intervals of 5 to 15 seconds according to designation of music display fields 602 to 608 at time points t2, t3, t4, t5, t6, t7, and t8. Is done. Thereby, the music data S2 to S8 are reproduced in order. Since the music data S4 and S6 have already been analyzed, the music data S4 and S6 are not analyzed.

  At the time t3, the analysis of the music data S2 is not completed, so the analysis of the music data S3 is put on standby. When the analysis of the music data S2 ends at time t30, the analysis of the music data S3 is started. At the time points t5 and t6, the analysis of the music data S3 is not completed, so that the analysis of the music data S5 is put on standby. Even at the time t7, the analysis of the music data S3 is not completed, so that the analysis of the music data S5 and S7 is put on standby. When the analysis of the music data S3 ends at time t70, the analysis of the music data S5 is started.

  At time t8, the analysis of the music data S5 has not been completed, so the analysis of the music data S7 is put on standby. When the analysis of the music data S5 is completed at time t80, the analysis of the music data S7 is started. When the analysis of the music data S7 ends at time t90, the analysis of the music data S8 is started. The analysis of the music data S8 ends at time t100. The analysis of the music data S8 ends 55 seconds after the selection of the music data S8. Thus, in this example, the priority of analysis is high in the order of music data selection.

  In the second operation example of FIG. 6, the music data S2 to S5 are selected in order at the time points t2, t3, t4, and t5 by the designation of the music display fields 602 to 605. Thereby, the music data S2 to S5 are reproduced in order. Since the music data S4 has already been analyzed, the music data S4 is not analyzed. The operation from time t2 to t5 is the same as the operation in FIG.

  Thereafter, the reanalysis of the music data S6 is instructed by the designation of the reanalysis button 630 in the music display column 606 at time t6. The music data S7 and S8 are sequentially selected by the designation of the music display fields 607 and 608 at the times t7 and t8.

  At the time points t6 and t7, the analysis of the music data S3 is not completed, so that the analysis of the music data S5, S6, and S7 is put on standby. When the analysis of the music data S3 is completed at time t70, the analysis of the music data S6 is started with priority over the analysis of the music data S5. At time t8, the analysis of the music data S6 has not been completed, so the analysis of the music data S5, S7, S8 is put on standby. When the analysis of the music data S6 ends at time t81, the analysis of the music data S5 is started. When the analysis of the music data S5 is completed at time t82, the analysis of the music data S7 is started. When the analysis of the music data S7 is completed at time t91, the analysis of the music data S8 is started. The analysis of the music data S8 ends at time t101. The end of the analysis of the music data S8 is 75 seconds after the selection of the music data S8. In this example, the priority of analysis of the music data S6 to be reanalyzed is the highest at the time of the reanalysis instruction by the reanalysis button 630.

  In the third operation example of FIG. 7, the music data S2 to S5 are sequentially selected by the designation of the music display fields 602 to 605 at the time points t2, t3, t4, and t5. Thereby, the music data S2 to S5 are reproduced in order. Since the music data S4 has already been analyzed, the music data S4 is not analyzed. The operation at time points t1 to t5 is the same as the operation in FIG.

  Thereafter, the music data S7 is selected by the designation in the music display field 607 at time t6. Thereby, the music display column 607 is selected. At time t6, the analysis of the music data S3 has not been completed, so the analysis of the music data S5, S7 is put on standby.

  Thereafter, music information display is instructed by the designation of the music information display button 650 at time t7. Thereby, a music information display screen for displaying the music information of the music data S7 corresponding to the music display field 607 is displayed.

  At time t7, the analysis of the music data S3 has not been completed, so the analysis of the music data S5, S7 is put on standby. When the analysis of the music data S3 is completed at time t70, the analysis of the music data S7 is started with priority over the analysis of the music data S5. The music information extracted by analyzing the music data S7 is sequentially displayed on the music information display screen. When the analysis of the music data S7 is completed at time t71, the analysis of the music data S5 is started. The analysis of the music data S5 ends at time t72. In this example, the priority of analysis of the music data S7 selected at the time of the music information display instruction by the music information display button 650 is the highest.

  The analysis of the music data S7 ends 40 seconds after the selection of the music data S7 and 35 seconds after the music information display instruction. On the other hand, the end of the analysis of the music data S5 is 60 seconds after the selection of the music data S5. When the music information display instruction for the music data S7 is not given, the music data S5 is analyzed prior to the music data S7. In this case, the end of the analysis of the music data S7 is 50 seconds after the selection of the music data S7. On the other hand, the analysis of the music data S5 ends 30 seconds after the selection of the music data S5.

(5) Operation of Acoustic Signal Analysis Control Device 100 FIGS. 8 to 13 are flowcharts showing analysis control processing performed by the acoustic signal analysis control device 100. FIG. The analysis control processing of FIGS. 8 to 13 is performed by the CPU 11 of FIG. 1 executing the acoustic signal analysis control program stored in the ROM 10 or the storage device 13. In the flowcharts of FIGS. 8 to 13, the determination step is represented by a horizontally long hexagon.

  The analysis waiting list and the analysis in progress flag are stored in the RAM 9 or the storage device 13. In the analysis waiting list, information for specifying music data in the analysis standby state (hereinafter referred to as specific information) is registered. The analyzing flag is turned on when any music data is being analyzed, and the analyzing flag is turned off when any music data is not being analyzed. In the following description, the selected music data is referred to as a selected music, and the music data being analyzed is referred to as an analyzing music.

  First, the CPU 11 performs an initialization process (step S11). As a result, the analysis waiting list becomes empty, the analyzing flag is turned off, and the currently selected music and the currently analyzed music are “none”. Further, the CPU 11 displays the display screen 600 of FIG. 3 on the touch panel display 6 (step S12). The plurality of music display fields 601 to 608 of the display screen 600 are set to a non-selected state, and the plurality of reproduction displays 610 are set to an off state. An analysis result 640 indicating the tempo is displayed in the music display column corresponding to the analyzed music data.

  Next, the CPU 11 determines whether an end instruction has been detected (step S13). The user can instruct the end by specifying the end button 680 of FIG. If an end instruction is detected, the CPU 11 performs an end process (step S14). In this case, when the music data is being reproduced, the CPU 11 stops the reproduction. When the music data is being analyzed, the CPU 11 finishes analyzing the music data being analyzed, and then stores the extracted music information in the storage device 13 in association with the analyzed music data. Stop the analysis.

  If an end instruction is not detected in step S13, the CPU 11 determines whether an operation for any piece of music data on the display screen 600 has been detected (step S15). When an operation on any piece of music data is detected, processing at the time of operation detection shown in FIGS. 9 to 12 described later is performed (step S16). In this example, in order to simplify the description, the description of the process at the time of displaying the attached information by the attached information display button 660 is omitted. After the process at the time of detecting the operation is completed, the CPU 11 proceeds to step S17.

  If no operation on any music data is detected in step S15, the CPU 11 determines whether or not the analyzing flag is on (step S17). When the in-analysis flag is on, an analysis start control process shown in FIG. 13 described later is performed (step S18). After finishing the analysis start control process, the CPU 11 proceeds to step S19.

  If the in-analysis flag is off in step S17, the CPU 11 performs other processing (step S19). Other processing includes volume adjustment processing, screen setting processing, and the like. Usually, the dynamics of music data after production is standardized. Thereby, in a general music reproducing apparatus, the music data is reproduced at the standard volume level. On the other hand, when the music data is selectively reproduced for music production using the electronic music apparatus 1 according to the present embodiment, the user may feel that the volume is too high. In this case, if the volume level of the music data stored in the storage device 13 is reduced by, for example, about 6 dB from the standard volume level, the volume is often easy to hear. Therefore, the CPU 11 may adjust the volume level of the music data stored in the storage device 13 to a certain level (a predetermined amount) lower than the standard volume level by the volume adjustment process. In addition, when reproducing | regenerating and analyzing the selected music data, CPU11 may adjust the volume level of the music data by a volume adjustment process.

  Further, in other processing of step S19, processing at the time of detection of the all-music data analysis instruction may be performed. The user can instruct all music data analysis by designating the all music data analysis button 670 of FIG. When the all-music data analysis instruction is detected in a state where the analyzing flag is off, re-analysis is instructed in order for all the music data displayed on the display screen 600 of FIG. In this case, the CPU 11 starts reanalysis of the first music data, and sequentially registers the specific information of the other music data in the analysis waiting list. On the other hand, when the all-music data analysis instruction is detected in the state where the analyzing flag is on, the CPU 11 once deletes the specific information registered in the analysis waiting list and displays the specific information of all the music data in the analysis waiting list. Register in order.

  Next, a process at the time of operation detection of step S16 of FIG. 8 is demonstrated, referring FIGS. 9-12. The CPU 11 determines whether or not a music information display instruction by the designation of the music information display button 650 is detected (step S21). When the music information display instruction is not detected, the CPU 11 determines whether or not the reanalysis instruction by the designation of the reanalysis button 630 is detected (step S22). When the reanalysis instruction is not detected, the CPU 11 determines whether or not the selection instruction by the designation of the music display fields 601 to 608 is detected (step S23).

  When the selection instruction is detected, the CPU 11 determines whether or not the music data for which selection has been instructed is the currently selected music (step S24). If the music data instructed to select is not the currently selected music, the CPU 11 changes the display mode of the currently selected music to the non-selected state (step S25). Further, the CPU 11 determines whether or not the currently selected music is being reproduced (step S26). If the currently selected music is being played back, the CPU 11 stops the playback of the currently selected music and changes the playback display 610 corresponding to the currently selected music to an off state (step S27). Further, the CPU 11 changes the selected music to the selected music data (step S28). If the currently selected music is not being reproduced in step S26, the CPU 11 proceeds to step S28. Next, the CPU 11 changes the display mode of the currently selected music to the selected state (step S29). Further, the CPU 11 starts the reproduction of the selected music and changes the reproduction display 610 corresponding to the selected music to the on state (step S30).

  For example, when the music display field 601 in FIG. 3 is in a selected state, the user designates the music display field 602. In that case, the music display field 601 is changed to a non-selected state, the reproduction of the music data S1 is stopped, and the reproduction display 610 of the music display field 601 is changed to an off state. Further, the music display column 602 is changed to the selected state, and the reproduction of the music data S2 is started, and the reproduction display 610 of the music display column 602 is changed to the on state.

  Thereafter, the CPU 11 determines whether or not the selected music has been analyzed (step S31 in FIG. 10). If the currently selected music has not been analyzed, the CPU 11 determines whether or not the analyzing flag is off (step S32). If the analyzing flag is on, the CPU 11 determines whether or not the selected music is an analyzing music (step S33). That is, the CPU 11 determines whether or not the selected music data is being analyzed. If the selected music is not an analyzed music, the CPU 11 determines whether or not there is specific information of the selected music in the analysis waiting list (step S34). If there is no specific information of the selected music in the analysis waiting list, the CPU 11 adds the specific information of the selected music to the end of the analysis waiting list (step S35), and proceeds to step S17 in FIG.

  For example, when the music data S2 in the music display column 602 in FIG. 3 has not been analyzed and other music data is being analyzed, the specific information of the music data S2 is added to the end of the analysis waiting list. Thereby, the analysis of the music data S2 is made to wait.

  If the analyzing flag is off in step S32, the CPU 11 turns on the analyzing flag (step S40). Further, the CPU 11 sets the music being analyzed as the music being selected (step S41), and starts analyzing the music being analyzed (step S42). Thereafter, the CPU 11 proceeds to step S17 in FIG.

  For example, when the music data S2 in the music display column 602 in FIG. 3 has not been analyzed and no other music data is being analyzed, the CPU 11 starts analyzing the music data S2.

  If the selected music has been analyzed in step S31, if the selected music is in analysis in step S33, and if there is specific information on the selected music in the analysis waiting list in step S34, the CPU 11 Proceed to step S17 of FIG.

  For example, when the music data S2 in the music display field 602 in FIG. 3 is selected, the music data S2 has been analyzed, or the music data S2 is being analyzed, or other music data is being analyzed and When the music data S2 is in the analysis waiting list, the analysis of the music data S2 by the detection of the selection instruction for the music data S2 is not performed.

  If the music data selected and instructed in step S24 in FIG. 9 is the currently selected music, the CPU 11 determines whether or not the currently selected music is being reproduced (step S43). When the currently selected music is being played back, the CPU 11 stops the playback of the currently selected music and changes the playback display 610 corresponding to the currently selected music to an off state (step S44), and proceeds to step S17 in FIG. . If the music data corresponding to the selected music is not being played back in step S43, the CPU 11 starts playing the selected music and changes the playback display 610 corresponding to the selected music to the on state (step S45). Proceed to step S17 of FIG.

  For example, when the music display column 601 in FIG. 3 is selected and the playback display 610 is on, the user designates the same music display column 601. In this case, the reproduction of the music data S1 is stopped and the reproduction display 610 in the music display column 601 is changed to an off state. On the other hand, when the music display column 601 in FIG. 3 is selected and the reproduction display 610 is off, the user designates the same music display column 601. In that case, the reproduction of the music data S1 is started and the reproduction display 610 of the music display column 601 is changed to the on state.

  When the reanalysis instruction by the reanalysis button 630 is detected in step S22, the CPU 11 proceeds to step S50 in FIG. In step S50, the CPU 11 determines whether or not the music data instructed to be reanalyzed is the currently selected music. If the reanalyzed music data is not the currently selected music, the CPU 11 changes the display mode of the selected music to a non-selected state (step S51). Further, the CPU 11 determines whether or not the currently selected music is being reproduced (step S52). If the currently selected music is being played back, the CPU 11 stops the playback of the currently selected music and changes the playback display 610 corresponding to the currently selected music to an off state (step S53). Further, the CPU 11 changes the selected music to music data instructed to be reproduced and analyzed (step S54). If the currently selected music is not being reproduced in step S52, the CPU 11 proceeds to step S54.

  Next, the CPU 11 changes the display mode of the currently selected music to the selected state (step S55). At this time, the CPU 11 may start the reproduction of the selected music and change the reproduction display 610 corresponding to the selected music to the on state.

  For example, when the music display column 605 in FIG. 3 is selected, the user designates the reanalysis button 630 in the music display column 606. In that case, the music display column 605 is changed to a non-selected state, the reproduction of the music data S5 is stopped, and the reproduction display 610 of the music display column 605 is changed to an off state. In addition, the music display column 606 is changed to the selected state. At this time, the reproduction of the music data S6 may be started and the reproduction display 610 of the music display field 606 may be changed to the on state.

  Thereafter, the CPU 11 determines whether or not the analyzing flag is off (step S56). When the analyzing flag is on, the CPU 11 determines whether or not the selected music is an analyzing music (step S57 in FIG. 12). That is, the CPU 11 determines whether or not the selected music data is being analyzed.

  If the selected music is not an analyzed music, the CPU 11 determines whether or not there is specific information on the selected music in the analysis waiting list (step S58). If there is specific information of the selected music in the analysis waiting list, the CPU 11 moves the specific information of the selected music to the head of the analysis waiting list (step S59), and proceeds to step S17 in FIG. If there is no specific information of the selected music in the analysis waiting list in step S58, the CPU 11 adds the specific information of the selected music to the head of the analysis waiting list (step S60), and the CPU 11 proceeds to step S17 in FIG. .

  For example, when the reanalysis button 630 in the music display column 606 in FIG. 3 is designated and other music data is being analyzed, the specific information of the music data S6 is registered at the head of the analysis waiting list. Thereby, reanalysis of the music data S6 is made to wait. In this case, the priority of analysis of the music data S6 is the highest.

  When the analyzing flag is off in step S56 of FIG. 11, the CPU 11 turns on the analyzing flag (step S61). Further, the CPU 11 sets the music being analyzed as the music being selected (step S62), and starts analyzing the music being analyzed (step S63). Thereafter, the CPU 11 proceeds to step S17 in FIG.

  For example, when the reanalysis button 630 in the music display column 606 in FIG. 3 is designated and no other music data is being analyzed, reanalysis of the music data S6 is immediately started.

  If the music data for which reanalysis is instructed in step S50 of FIG. 11 is the currently selected music, the CPU 11 proceeds to step S56, and after the processing of steps S61 to S63 or the processing of steps S57 to S60 of FIG. The process proceeds to step S17.

  For example, when the music display field 606 corresponding to the analyzed music data S6 in FIG. 3 is selected, the user designates the reanalysis button 630 in the music display field 606. When other music data is being analyzed, the specific information of the music data S6 is registered at the head of the analysis waiting list. Thereby, reanalysis of the music data S6 is made to wait. In this case, the priority of analysis of the music data S6 is the highest.

  If the music information display instruction by the music information display button 650 is detected in step S21 in FIG. 9, the CPU 11 proceeds to step S70 in FIG. In step S70, the CPU 11 determines whether there is a selected music piece. If there is a music piece being selected, the CPU 11 displays a music information display screen corresponding to the music piece being selected on the touch panel display 6 (step S71). On the music information display screen, the music information already extracted by the analysis is displayed. The music information displayed on the music information display screen is updated as the music data analysis progresses. If no music information is extracted, no music information is displayed on the music information display screen.

  If the analysis of the music data is not finished, first, information not related to the analysis such as waveform data and time axis is displayed on the music information display screen, and the music information is displayed after the analysis is completed, or The music information extracted as the analysis progresses may be displayed on the music information display screen in the definite order.

  Thereafter, the CPU 11 determines whether or not the selected music has been analyzed (step S72). If the currently selected music has not been analyzed, the CPU 11 proceeds to step S56 and performs the processing of steps S56 to S63 in the same manner as when the reanalysis instruction is detected.

  For example, when the music display column 607 in FIG. 3 is in the selected state, the user designates the music information display button 650. In this case, a music information display screen corresponding to the music data S7 is displayed. When other music data is being analyzed, the specific information of the music data S7 is registered at the top of the analysis waiting list. Thereby, reanalysis of the music data S7 is made to wait. In this case, the priority of analysis of the music data S7 is the highest. If no other music data is being analyzed, reanalysis of the music data S7 is immediately started.

  If there is no selected music in step S70 of FIG. 11 and if the selected music has been analyzed in step S72, the CPU 11 proceeds to step S17 of FIG. If no selection instruction is detected in step S23 of FIG. 9, the CPU 11 proceeds to step S17 of FIG.

  Next, the analysis start control process in step S18 of FIG. 8 will be described with reference to FIG. The CPU 11 determines whether or not the analysis of the music being analyzed has been completed (step S81). When the analysis of the music under analysis is completed, the CPU 11 stores the music information extracted from the music under analysis in the storage device 13 in association with the music under analysis (step S82). In this case, the CPU 11 may display the extracted music information in the order of extraction. Further, the CPU 11 displays the tempo of the music information extracted from the music being analyzed as the analysis result 640 in the corresponding music display column of the display screen 600 (step S83). In this case, the analysis result 640 indicating the tempo is a display mode indicating that the analysis has been completed.

  Next, the CPU 11 determines whether or not the analysis waiting list is empty (step S84). If the analysis waiting list is empty, the CPU 11 turns off the analyzing flag (step S85), and initializes the music being analyzed to “none” (step S86). Thereafter, the CPU 11 proceeds to step S19 in FIG.

  If the analysis waiting list is not empty in step S84, the CPU 11 sets the music data corresponding to the specific information registered at the head of the analysis waiting list as the music being analyzed (step S87). Thereafter, the CPU 11 deletes the specific information registered at the head of the analysis waiting list (step S88).

  Next, the CPU 11 determines whether or not an analysis condition corresponding to the music being analyzed is designated (step S89). When the analysis condition corresponding to the music under analysis is designated, the CPU 11 starts analyzing the music under analysis according to the designated analysis condition (step S90). If the analysis condition corresponding to the music under analysis is not specified in step S89, the CPU 11 starts analyzing the music under analysis without the analysis conditions (step S91).

(6) Effects of the Embodiment According to the acoustic signal analysis control device 100 according to the present embodiment, the user selects and reproduces other music data and reanalyzes other music data while analyzing one music data. Alternatively, when an operation such as display of music information related to other music data is instructed, an operation related to other music data is executed. In this case, the analysis of one piece of music data is continued and the analysis of the other piece of music data is put on standby. Therefore, extraction of music information from music data that is already being analyzed is ensured regardless of the timing of the user's operation instruction.

  Further, in conjunction with the operation related to the music data, the music data is analyzed or registered in the analysis waiting list. Thereby, the operation regarding the music data and the instruction for analyzing the music data are not complicated. Therefore, the user can extract music information from the music data by an efficient operation instruction.

  Furthermore, when the user selects music data by designating the music display field, the selected music data is reproduced. Moreover, after the analysis of the music data corresponding to the specific information registered in the analysis waiting list is completed, the analysis of the selected music data is started. Thereby, the user can analyze the music data in the order of selection by selecting the music data in an arbitrary order.

  In addition, when the user gives an instruction to reanalyze the music data by specifying the reanalyze button 630, the music data corresponding to the specific information in the analysis waiting list is prioritized after the analysis of the music data being analyzed is finished. Thus, the music data instructed to be reanalyzed is analyzed. Thereby, the user can preferentially analyze the music data instructed to be reanalyzed.

  In addition, when the user gives an instruction to display music information by specifying the music information display button 650, the music information of the music data being selected is displayed and the analysis is performed after the analysis of the music data being analyzed is completed. The music data being selected is analyzed in preference to the music data corresponding to the specific information in the waiting list. Thereby, the user can preferentially analyze the music data being selected when the music information display instruction is given.

(7) Example of use of music information When a tempo is extracted from phrases of a plurality of rhythms such as drums, the user saves a favorite phrase out of the plurality of phrases together with the tempo extracted as a rhythm pattern, and performs the performance. In addition, it is possible to select and use a rhythm pattern having a tempo that matches the performance of the user.

  When the tempo and chord are extracted from a plurality of music data, the user can select accompaniment style data in which a recommended tempo close to the extracted tempo is set. Thereby, the user can perform automatic accompaniment by the accompaniment style data selected using the extracted chord while reproducing the music data. In addition, when the user performs, it is possible to notify the user of a state in which the user's performance tempo is delayed or too fast based on the extracted tempo by voice or display. Furthermore, the tempo extracted from the music data can be used as a reference for creating a play list (play list).

  Based on the extracted code, it is possible to automatically generate a harmony sound in accordance with the reproduction of the music data. When the user performs along with the reproduction of the music data, the user's performance can be corrected to match the extracted chord. Thereby, a user's performance can be automatically matched with music data. Further, a chord sequence, automatic accompaniment data, harmony data, or the like can be generated based on the extracted chord.

  When the tempo and beat point are extracted from the music data, the performance position can be shown to the user on the score displayed on the touch panel display 6. In addition, a metronome sound can be generated in accordance with the extracted tempo and beat point. Furthermore, it is possible to perform a performance guide instructing the user to press the key based on the performance guide data corresponding to the music data and the extracted tempo and beat point. When note information, beat points, and time signatures are extracted, score display data can also be generated.

(8) Other Embodiments Selection of music data and start / stop of reproduction of music data may be instructed by different operations. In this case, the playback display 610 is changed to a playback button, and playback start / stop is assigned to ON / OFF of the playback button. Further, only the music data is selected by the designation of the music display fields 601 to 608. Furthermore, a playback instruction may be automatically performed in the order of music pieces set in advance as in a playlist. In this case, an instruction may be given so that only the beginning portion (about several seconds) of each piece of music data is automatically reproduced in order.

  When analysis of a plurality of music data is in a standby state, analysis of music data that is selected (reproduced) at a time closest to the end of analysis of the music data being analyzed may be preferentially started. A common reanalysis button may be provided for a plurality of music data. In this case, re-analysis of the music data selected when the user designates a common re-analysis button is instructed.

  When the analysis program is updated due to version upgrade of the acoustic signal analysis control program, all music data may be changed to an unanalyzed state. In this case, music information can be extracted with high accuracy by analyzing each piece of music data using a new analysis program. Further, reanalysis may be performed when the analysis program is updated or when the user gives analysis conditions. Furthermore, when there are a plurality of analysis methods, re-analysis may be performed when the user switches the analysis method.

  A function for adding, deleting, or editing music data on the display screen 600 may be provided. When music data is added or edited, the music data becomes unanalyzed, and analysis is instructed when a selection (playback start / stop) instruction, music information display instruction, or reanalysis instruction is detected. Is done.

  The priority of analysis of music data that is the target of a specific instruction such as a music information display instruction or a reanalysis instruction may be arbitrarily set. For example, the user may be able to set the specific information of the music data that is the target of a specific instruction to be registered at an arbitrary position other than the top or the end of the analysis waiting list. Thereby, the user can arbitrarily set the start timing of the music data analysis when the specific instruction is detected.

  You may determine with the analysis of music data having been completed when the analysis of the preset part of music data was completed. Further, a function for setting and storing the analysis completion position for each piece of music data may be provided, and it may be determined that the analysis is completed when the analysis from the beginning of the music data to the analysis completion position is completed. Similarly, a function for setting and storing the analysis start position for each piece of music data is provided, and even if it is determined that the analysis is completed when the analysis from the analysis start position to the end (or the analysis completion position) of the music data is completed. Good. Further, the end of the analysis may be indicated by lighting a button corresponding to each song name, displaying characters or symbols displayed corresponding to each song name, or changing the display mode of the song name.

  An operation such as selection of music data may be instructed by using a switch such as a button arranged near the display screen 600. Instead of the touch panel display 6, a display such as a liquid crystal display or an organic EL (electroluminescence) display is provided. An apparatus may be provided, and an input device such as a mouse or a switch for instructing an operation such as selection of music data may be provided. A plurality of pieces of music data may be stored in an external storage device 15 that can be referred to from the electronic music apparatus 1 or the acoustic signal analysis control program, an external apparatus such as another electronic music apparatus or a server.
